In 2018, affected by the decline in domestic automobile production and sales, the output of motor vehicle exhaust gas purification catalysts was 56 million liters, down 3.4% year-on-year. The process technology continued to break through and developed a gasoline vehicle exhaust gas purification catalyst integration technology that meets the national VI emission standards. The output of petroleum cracking catalyst was 200,000 tons, which was the same as that of the same period of last year. The catalytic efficiency was improved, and the crude oil processing volume increased by 6.8%. (Source: China Rare Earth Industry Association)
